Free Will

ESPor "extra sensorial" perception, has been studied ‘scientifically’ for a while. Recent reviews of those studies include
Delanoy (pdf),
Utts (pdf), and
Hyman (html). The results are
somewhat impressive; statistically it is almost impossible that they might have
happened by chance. However, there have inspired more controversy than answers.
Theoretically, they seem to fit more into mystical mumbo-jumbo talk than any
scientific explanation of the universe. Empirically, many doubts have been
raised regarding the impartiality of the experimenters, etc, although the available
evidence seems sufficiently massive and serious to query those doubts. Whatever
details we may find out in the future regarding the scope, functioning and
reality of ESP, its possibility has already interesting implications both to
the philosophy of mind debate and for neuroscience research.
